I can't comment on the drum machine, but I have a friend that has the Zoom recorder. It does a great job. He played me some tracks that he recorded the other day at a gig and it sounded really nice.
I recently purchased the Tascam DR-05 handheld recorder. Great tool! I would highly recommend a recorder such as the Tascam or Zoom. It is nice for recording rehearsals, practice, etc... Great learning tool.
